Abstract

Copyright © 2018 by the International Society of Offshore and Polar Engineers (ISOPE) Laboratory experiments have been carried out in a piston-driven wave flume to investigate the solitary wave impact on three types of vertical cylindrical objects, including the vertical cylinder, cone and bell-shaped lighthouse structure. First, the quality of the generated waves is examined by comparing their profiles with the theoretical solutions. The range of piston movements that generates good-quality solitary waves is determined. The scattering of solitary waves around geometrically different vertical structures is then focused on. The wave heights around the structures are measured in detail, from which the wave impact force is derived. The results regarding vertical cylinders agree well with the past research outcomes. It shows that the vertical cone structure experiences the largest impact force. Although the bell-shaped lighthouse structure incurs slightly larger impact force than the vertical cylinder, it has a much larger and thus more stable base to resist the overturning moment. The findings confirm the good mechanical performance of some of the old lighthouse structures, which have existed for around 200 years.
